FIELD OF INVENTION

The embodiments described herein relate to insulators and clamps forelectrical utility lines. The clamping insulators of the presentembodiments integrate an improved clamp to secure the wires to theinsulators, as well as features to provide greater bearing force on thewire and to provide easier installation and removal of insulators.

BACKGROUND

An electrical insulator acts as a barrier between the electricityflowing in a charged electrical utility line and the ground. Forbrevity, the term “electrical wire” or, for brevity, “wire” (includingplural forms), is used herein to encompass various conduits throughwhich electricity passes including wires, cables, and utility lines.

Conventionally, wires are attached to and supported by poles, towers,and other support structures by both an insulator and a clampingarrangement to secure the live line to the insulator. Typically, theclamping arrangement includes an insulator and a clamping devicecomprising a body member on which the line is placed and a clamping armwhich is seated over the line and bolted to the body member using bolts,nuts, and washers. In other conventional examples, the electrical wireis secured to the insulator by the use of a vice-like arrangement thatpresses against the wire from the left and right side by tightening thenuts and bolts.

Electrical utility workers, or linemen, are generally not allowed totouch the insulator through which a charged wire passes. Instead, thelineman are required to utilize an insulated pole known as a “hot stick”or “switch stick” to protect them from electric shock and to providephysical separation from the insulator to reduce the chances of burns.Hot sticks are usually made of fiberglass and are made in variety oflengths, from a few feet up to forty feet in length. However, most hotsticks are typically six to ten feet in length.

While insulated hot sticks provide safe contact with energizedequipment, their use presents a number of disadvantages in installing,tightening, removing, and loosening the typical conductor from aninsulator. This operation requires the lineman to meticulouslymanipulate the hot stick in order to tighten or loosen the nuts andbolts of the typical clamping arrangement. Typically, said bolt ispositioned parallel to the ground which makes it difficult to access theeyelet or bolt with a hot stick. This extensive and meticulous operationpresents obvious safety hazards to the lineman and results in aninefficient and time consuming process for most electrical line crews.

The conventional electrical power line clamp presents otherdisadvantages. This includes the opportunity for parts, such as nuts andbolts, to be dropped during the installation or removal process. Ratherthan carrying a clamping apparatus that also serves as an insulator, theconventional arrangement also requires linemen to carry separateinsulators and clamps for the installation and removal process.Moreover, because conventional electrical clamps are not universallyadapted to secure electrical wires of various diameters, linemen areoften required to carry a variety of clamp sizes for securing electricalwires of different sizes.

Some conventional clamping arrangements utilize a clamping devicecomprising a body member on which the line is placed and a clamping arm.The clamping arm is then seated over the line and bolted to the bodymember so they are hingebly connected. When the electrical wire issecured to the clamp in this typical arrangement, the electric wire runsparallel to the axis of the hinge that secures the clamping arm to thebody member and also runs perpendicular to the clamping arm itself.Furthermore, when the electrical wire is secured to the clamp in theconventional arrangement, the electrical wire is equidistant from theaxis of the hinge and the end of the clamping arm in the closed positionsuch that a “symmetrical fulcrum” effect is utilized to secure the wire.However, in this conventional arrangement the symmetrical fulcrum effectand the parallel relationship between the electrical wire and the axisof the hinge do not provide a sufficient bearing force directly on theelectrical wire to secure it in place. Herein, the term “axis” refer toan imaginary line about which rotation occurs (e.g., hinge axis 50) orthe term axis can be a reference line used in defining one or moreangles (examples include fixture axis 72 and longitudinal axis 78,described below).

Accordingly, there is a significant need for a clamping insulator thatprovides greater bearing force directly on the wire and can be easilymanipulated using a hot stick. Such an improvement would further reducecertain hazards to linemen and limit the time required for installationand removal of the insulator. There is a need for an integratedinsulator and clamp suitable for a variety of electrical wire diameters.Likewise, it is desirable for an insulated clamp to utilize an eyebolt,or a similar type of attachment, instead of nuts and bolts for securingthe wire to the insulator. Along with other features and advantagesoutlined herein, clamping insulators within the scope of presentembodiments meet these and other needs. In doing so, the inventiveapparatuses provide greater bearing force directly on the wire, easierinstallation and removal of the insulator. Moreover, the use of aneyebolt or a similar type of attachment for securing the clamp in theclosed position allows a lineman to easily manipulate the insulatedclamp by the use of a hot stick, and a clamping apparatus with insulatoradapted for accommodating a variety of wire diameters.

SUMMARY OF EMBODIMENTS

A clamping insulator, sometimes referred to herein as “clampingapparatus” or “clamp” for brevity, according to present embodimentsprovides greater direct bearing force directly to the wire, with easierinstallation and removal. Structurally, the clamps of the presentembodiments comprise a fixture for holding specific parts in certainpositions during engagement with a wire, i.e., for securing a firstclamp member in a position relative to a second clamp member asselectably chosen by a user. The present embodiments allow for easierand safer manipulation of the inventive clamping apparatus, such as by alineman using a hot stick, with the clamp able to self-adjust to securea variety of wire sizes.

For illustrative (and non-limiting) purposes, the present embodimentsare described with an eyebolt for the fixture, to secure the clampmembers in position relative to one another. However, any number ofother fixtures besides eyebolts are well known to persons of ordinaryskill in the art, which can be used easily with the inventive clamp forsecuring the positioning of the clamp members when the apparatus is inthe closed position. Accordingly, references to an eyebolt or an eyeletare not intended as limiting of the scope of embodiments.

Current embodiments provide for a clamping insulator with a first clampmember that can be either opened or closed relative to the second clampmember. In this way, the first clamp member is connected to the secondclamp member in a hinged relationship, i.e., hingebly. This hingeprovides a single axis of rotation for the first clamp member relativeto the second clamp member. In this embodiment, the hinge allows thefirst clamp member to simply be flipped or folded over upon the lowermember to a closed state in order to secure the electrical wire inplace. The first and second clamp members form a channel through whichthe electrical wire passes through. As will be explained in more detailbelow, in some embodiments the channel contains a series of grooveswhich are indentations in the channel surface for receiving at least oneinsert (shown in non-limiting fashion as a plurality of inserts in thefigures). The inserts are formed from known materials that can be usedto provide different holding and retention effects directly upon theelectrical wire by increasing the friction between the wire and theclamp. Examples of such materials include ceramics, polymers,semi-metallic, or metallic.

In some embodiments, an eyebolt is utilized as the fixture, which bothsecures the first and second clamp members together and allows a linemanto manipulate the clamp without manual contact. The eyebolt is hingeblyconnected to the first clamp member of the clamp, such that the eyeboltswivels upon the axis of this eyebolt hinge when the first clamp memberis closed or opened. When the clamp is manipulated from the openposition to the closed position by the use of a hot stick, the eyeboltengages a fixture receiving notch formed in the second clamp member.

In addition, when the clamp is manipulated from the open position to theclosed position, the clamp self-adjusts to secure electrical wires ofdifferent diameters. In some embodiments, a lineman can choose totighten the insulated clamp about the electrical wire based on theapplication and/or vary the clamping force by accessing the eyelet ofthe eyebolt with a hot stick, and rotating the eyebolt to tighten theclamp shut. In other embodiments, the eyebolt automatically locks inplace, without additional tightening with a hot stick, by merely beingfolded into the closed position.

In some embodiments, the first and second clamp members are arrangedwith corresponding angled regions such that when the first clamp memberis in the closed position and the eyebolt is automatically secured inplace, the eyebolt is positioned at an angle (e.g., including but notlimited to 30° in some embodiments) relative to the support structure onwhich the wire sits, making it easier for the lineman to access theeyelet with the hot stick. When the first clamp member is in the openposition and the eyebolt is not secured in placed to the lower member,the eyebolt is also positioned away from the support structure making iteasier for the lineman to flip the clamp closed.

The fixture axis rests in a compound angle that also allows orientationrelative the ground. This creates easier installation for the lineman byallowing hot stick access from below the plane of the electricallycharged wires. Existing vise type products position the eyebolt parallelto the ground requiring difficult access for installation unless thelineman positions themselves dangerously close to the adjacentelectrically charged wires.

In conventional insulators that position a wire relative to a utilitypole or support structure, the electrical wire runs parallel to the axisof the hinge of the clamping arm, perpendicular to the clamping armitself, and/or perpendicular to the body member on which the electricalline is placed. Further, in conventional insulators with clamping arms,the electrical line is placed equidistant between the axis of the hingeand the end of a clamping arm when in the closed position, such that theclamping arm creates a symmetrical fulcrum. However, this typicalclamping arrangement fails to provide a sufficient bearing forcedirectly on the electrical wire to secure it in place.

According to present embodiments, the electrical wire is placed at anangle relative to the axis of the hinge rather than running parallel. Inaddition, the wire is not equidistant between the axis of the hinge andthe end of the first clamp member when in the closed position. Rather,in these embodiments, the electrical wire is secured in place closer tothe hinge point than the point equidistant the hinge axis and the end ofthe first clamp member when in the closed position. These embodimentscreate a mechanical force marked by an “asymmetrical fulcrum” effect inwhich more surface area of the clamp is applied to the wire. As comparedto other conventional insulators, the asymmetrical fulcrum effect of thepresent embodiments results in more pressure directly on the wire tosecure it in place (e.g. 1.3 times).

MULTIPLE EMBODIMENTS AND ALTERNATIVES

FIG. 1 shows clamping insulator 5 in the closed position according tomultiple embodiments and inventions. Clamp 15 includes first clampmember 18 and second clamp member 28. First clamp member 18 is attachedrotatably to second clamp member 28 by hinge 45. Clamping insulator 5consists of insulator 10 being coupled to and in non-electrical contactwith second clamp member 28. Insulator 10 is positioned relative tosecond clamp member 28 in a manner that each is not capable of receivingand transferring electrons from one to the other. Insulator 10 may bemade from a variety of insulating materials such as clay, plastic,glass, mica, teflon, perfluoroalkoxy, rubber, HDPE or others. In someembodiments, insulator 10 includes hollow region 12 by which theinsulator portion 10 of clamping insulator 5 is configured to be mountedto a support structure such as a pole or tower. Because of how insulator10 is fitted over and otherwise positioned relative to one of thesesupport structures, hollow region 12 generally defines a longitudinalaxis 78 as illustrated in FIGS. 9a and 10. The entire assembly ofclamping insulator 5 is made from nonconductive material. In someembodiments, insulator 10 and second clamp member 28 are both sectionsof clamping insulator 5. Insulator 10 and second clamp member 28 are notseparate components attached together.

It will be appreciated that in some embodiments first clamp member 18rotates about hinge 45 relative to second clamp member 28. For example,external rotation is denoted by arrow 17 shown in FIG. 1 and internalrotation denoted by arrow 17′ as shown in FIG. 3. In this regard,external rotation is associated with clamp opening and internal rotationis associated with clamp closure. Accordingly, internal rotationproduces the clamping force on an electrical cable or other wire to besecurely positioned relative to a support structure, while externalrotation releases that force.

Embodiments shown in FIG. 1 include first clamp member 18 havingprotrusion 20 and first angled region 22. Second clamp member 28consists of second angled region 32 that corresponds to first angledregion 22 of first clamp member 18. Second clamp member 28 furthercomprises a concave region forming recess 30 to receive protrusion 20when clamping insulator 5 is in the closed position. Recess 30 isconfigured to accommodate the wire when first clamp member 18 isexternally rotated so the wire can occupy the recess. After internalrotation of first clamp member 18, protrusion 20 is configured tocontact the wire received into recess 30.

As shown in later figures, including without limitation FIGS. 3, 8, 10,and 11, when first clamp member 18 engages second clamp member 28, firstclamp member 18 and second clamp member 28 define hinge hole 48 toreceive hinge 45. Protrusion 20 and recess 30 define a series of grooves40 to receive inserts 42. Optionally, at least one insert 42 ispositioned on a surface of protrusion 20 to provide this frictioneffect. In the illustrated embodiment, inserts 42 are corrugated.However, inserts of different texture and material may be used toprovide a variety of retention forces, as needed, directly upon theelectrical wire.

As will be illustrated in later figures, including without limitationFIGS. 7 and 11, eyebolt 52 and eyebolt sleeve 65 are connected to clamp15. Eyebolt 52 includes eyelet 55 to receive a hot stick which can bemanipulated to secure an electrical wire in place to insulated clamp 5.Eyebolt 52 also consists of threaded screw 58, and nut 60 and washer 62that are located on the distal end of eyebolt 52 between threaded screw58 and eyelet 55. Eyebolt sleeve 65 includes eyebolt sleeve hole 68 toreceive eyebolt 52, and in some embodiments sleeve 65 fits securelywithin a first fixture receiving notch 34 of first clamp member 18 asdiscussed below. As shown in FIG. 11, eyebolt sleeve hole 68 can bethreaded to receive and secure eyebolt 52. Eyebolt sleeve 65 alsoconsists of eyebolt sleeve hinge 70 which attaches to slot 25 of firstclamp member 18.

FIG. 2 shows clamping insulator 5 in the open position. As illustrated,first clamp member 18 is attached rotatably to second clamp member 28about hinge 45. First angled region 22 is where first fixture receivingnotch 34 is positioned along with slot 25 to receive eyebolt sleevehinge 70. In the open position, first clamp member 18 is positioned awayfrom second clamp member 28. Moreover, eyebolt sleeve hinge 70 issecured to slot 25 of first clamp member 18. Threaded screw 58 isinserted into eyebolt sleeve hole 68 to attach eyebolt 52 to first clampmember 18. Eyebolt 52 is positioned away from clamping insulator 5 toallow for easier manipulation of the clamping insulator by a lineman.

Also, a second angled region 32 of second clamp member 28 is where asecond fixture receiving notch 35 is positioned to receive the eyeboltwith the clamp in an internally rotated position resulting in clampclosure to a degree selected by a user of the clamp, i.e., sufficient toexert a force upon the wire as protrusion 20 contacts the wire.Accordingly, the idea of clamp closure is a relative term, the degree ofwhich may vary based on several factors including the diameter and sizeof the wire, but which in operation is marked by contact between theprotrusion of the first clamp member and the wire. In general, however,clamp opening occurs when the distance between the first angled regionand the second angled region (described below) becomes greater, whileclamp closure occurs when this distance becomes smaller to the pointwhere protrusion 20 contacts the wire.

To close clamping insulator 5, a lineman would use a hot stick to simplyflip or fold first clamp member 18 upon second clamp member 28, withouthaving to removing eyebolt 52, to secure an electrical wire in place.Upon closure of first clamp member 18 upon second clamp member 28,closing clamping insulator 5, and the internal rotation associated withclosure causes eyebolt 52 to engage second fixture receiving notch 35 ofsecond clamp member 28.

It will be understood that hollow region 12 of insulator 10 is notlimited to the precise arrangement and scale shown in FIG. 2. Instead,hollow region 12 can be adapted to connect to a variety of supportstructures.

FIG. 3 also shows clamping insulator 5 in the open position. Asillustrated, inserts 42 are attached to protrusion 20 and recess 30. Toclose clamping insulator 5, a lineman would simply fold first clampmember 18 closed without removing eyebolt 52. First clamp member 18would then rotate about hinge axis 50 into the closed position, and theelectrical wire would be secured in place. A lineman could then accesseyelet 55 with a hot stick to tighten clamp 15 about the electricalwire.

FIGS. 4-6 show clamping insulator 5 attached to support structure 80(not claimed) and illustrate electrical wire 74 (not claimed) engagedwith clamping insulator 5. FIG. 4 illustrates clamping insulator 5 inthe closed position securing electrical wire 74 in place. In FIG. 4,eyelet 55 has been accessed by a hot stick and tightened such that firstclamp member 18 and second clamp member 28 firmly engage and secureelectrical wire 74 to clamping insulator 5.

FIG. 5 illustrates a top view of clamping insulator 5 in the openposition, and electrical wire 74 rests in recess 30 of second clampmember 28. In some embodiments, as shown in this figure, first clampmember 18 also comprises first fixture receiving notch 34 and secondclamp member 28 also comprises second fixture receiving notch 35.

FIG. 6 illustrates a top view of clamping insulator 5 in the closedposition. As illustrated, hinge axis 50 is positioned at an anglerelative to electrical wire 74. When a lineman folds first clamp member18 into the closed position, first clamp member 18 rotates about hingeaxis 50, inserts 42 engage electrical wire 74, and eyebolt 52 engagessecond fixture receiving notch 35 to secure electrical wire 74 in place.As compared to conventional electrical power line clamps in which thehinge axis is parallel to the electrical wire, the angular relationshipbetween hinge axis 50 and electrical wire 74 results in more surfacearea of clamp 15 engaging with electrical wire 74 which provides greaterbearing force directly on the wire to secure it in place.

As shown in various figures, including without limitation FIGS. 3, 5 and10, hinge 45 serves as a pivot for first clamp member 18 to rotateinternally and externally relative to second clamp member 28.Additionally, recess 30 has formed therein a channel 38 extending at anangle relative to hinge 45. This arrangement is noticeable in FIG. 3 andFIG. 10 among others wherein inserts 42 are positioned in the channel 38as part of recess 30. From these views, it will be appreciated that inoperation, after it is situated with the clamping apparatus, the wire 74(best seen in FIG. 6) extends along channel 38 of second clamp member28. In that position, during closure marked by internal rotation denotedby arrow 17′, protrusion 20 of first clamp member 18 occupies the spaceassociated with recess 30 of second clamp member 28, while leaving emptyspace for wire 74 to extend along channel 38. In this way, wire 74 iscontacted by protrusion 20 of first clamp member 18 during internalrotation and closure.

FIG. 7 illustrates eyebolt 52 and eyebolt sleeve 65 connected to firstclamp member 18. FIG. 8 illustrates clamping insulator 5 in the openposition ready to secure an electrical wire. Second clamp member 28comprises a concave region forming recess 30 to receive protrusion 20when clamping insulator 5 is in the closed position. FIG. 9 illustratesclamping insulator 5 just after first clamp member 18—with a portion ofeyebolt 52 engaging a first fixture receiving notch 34—folded over as byinternal rotation onto second clamp member 28, with a different portionof eyebolt 52 engaging second fixture receiving notch 35. To secureclamp 15 about an electrical wire, a lineman would access eyelet 55 witha hot stick and rotate eyebolt 52 until eyebolt screw 58 is fullysecured into eyebolt sleeve 65. FIG. 10 illustrates clamping insulator 5after a lineman has fully secured eyebolt 52 into eyebolt sleeve 65.Protrusion 20 and recess 30 define channel 38 that the electrical wirepasses through.

As illustrated in FIGS. 9a and 10, second angled region 32 of secondclamp member corresponds to first angled region 22 such that when firstclamp member 18 is in the closed position, fixture axis 72 is positionedat an angle relative to longitudinal axis 78. As previously noted, whenfirst clamp member 18 is folded over second clamp member 28, it closesclamping insulator 5, and the internal rotation associated with closurecauses eyebolt 52 to engage second fixture receiving notch 35 of secondclamp member 28. When eyebolt 52 is positioned in both first fixturereceiving notch 34 and second fixture receiving notch 35, eyebolt 52 isoriented along fixture axis 72. In some embodiments, the arrangement offirst and second clamp members 18, 28 and the configuration of theirrespective angled regions 22, 32, is such that fixture axis 72 ispositioned at an angle relative to longitudinal axis 78 ranging fromabout 10°-40° (i.e., about 10 degrees-40 degrees). In some embodiments,this angle is 30°. In some embodiments, this angle formed by fixtureaxis 72 and longitudinal axis 78 will approximate or be equal to theangle of the second angled region 32 discussed in connection with thesecond clamp member. The angled position of eyebolt 52 makes it mucheasier for a lineman to access eyelet 55 with a hotstick to install orremove clamping insulator 5.

Referring now to FIG. 9b , first angled region 22 defines first lateraledge 81, and also defines a first angle 83 formed by first clamp memberlatitudinal axis 76 and first lateral edge 81. Second angled region 32defines second lateral edge 82, and also defines a second angle 84formed by second clamp member latitudinal axis 77 and second lateraledge 82. When first clamp member 18 undergoes internal rotation to asufficient degree, i.e., such that when protrusion 20 contacts the wire,it exerts a mechanical force directly upon the wire which is enhancedbecause of this intersection of the longitudinal axis 78 and fixtureaxis 72. This provides increased clamping force for the inventive clampscompared to conventional ones and the angle of the fixture facilitatesthe linemen in tightening or loosening the fixture, such as a fixture inthe form of an eyebolt with an eyelet.

In certain embodiments as shown in FIGS. 8-10, channel 38 is closer tohinge 45 than the point equidistant hinge axis 50 and the distal portionof second angled region 32 of second clamp member 28, such that clamp 15utilizes an “asymmetrical fulcrum” effect to secure an electrical wire.The “asymmetrical fulcrum” effect, combined with the angularrelationship between hinge axis 50 and electrical wire 74 illustrated inFIGS. 5 and 6, produces more pressure leading to greater clamping forcedirectly on the electrical wire to secure it in place.

Referring now to FIG. 11, insulator 10 is coupled to second clamp member28 of clamp 15. Inserts 42 are placed into the series of grooves 40 asdefined by protrusion 20 and recess 30. When first clamp member 18engages second clamp member 28, first clamp member 18 and second clampmember 28 define hinge hole 48 to receive hinge 45. After hinge 45 isinserted into and secured inside hinge hole 48, first clamp member 18rotates about hinge axis 50. Hinge axis 50 serves as the single axis ofswivel for first clamp member 18. Eyebolt sleeve hinge 70 attaches toslot 25, thereby securing eyebolt sleeve to first clamp member 18.Eyebolt 52 is secured to eyebolt sleeve 65 by threading screw 58 intoeyebolt sleeve hole 68.

In operation, clamping insulator 5 shall be pre-assembled. A linemanwill then attach clamping insulator 5 to support structure 80 withhollow region 12 fitted over the support structure. A lineman will thenuse a hotstick to open clamping insulator 5 and rest electrical wire 74onto recess 30 of second clamp member 28. To close the clampinginsulator, a lineman would simply flip or fold first clamp member 18over upon second clamp member 28, without removing eyebolt 52, in orderto secure electrical wire 74 in place. A lineman would then accesseyelet 55 with a hot stick and rotate eyebolt 52 until first clampmember 18 and second clamp member 28 fully secure electrical wire 74.
